Definition--Measures of Central Tendency--Average Speed	Average Speed Topic Statistics Definition Average speed is the total distance traveled divided by the total time taken. Description This concept finds application in areas such as physics, transport, and everyday scenarios like calculating travel time. For example, if a car travels 300 km in 3 hours, the average speed is Average Speed = 300 km / 3 hours = 100 km/h. Understanding average speed is key in mathematics as it helps contextualize rate and distance problems in real-life situations.	Data Analysis
